I enjoyed the Raptor Center, but I would not place it as a #1 thing to do as it appears on TA. I enjoyed the Totem Park more so, where you can spend a good amount of time strolling, watching eagles in the wild, and taking pictures of totem poles – all this for free.
At the Raptor Center, you pay admission, and it does not take long at all to see the whole Center.
However, the Center is an excellent opportunity to get a close-up photo of an eagle (although there will be cage wires in the foreground).
The Raptor Center is right next to the Totem Park, so you can easily do them both. In fact, you can easily see a few sites on your own without booking through the expensive cruise excursions. For instance, we did the Russian Bishop’s House, Totem Park, and the Raptor Center – all on foot and on our own. We even had time to explore the town as well afterwards.
